citizen of. the United States, residing at Fort Smith, in the county of Sebastian and the :State .of Arkansas,.have invented certain new and useful: Improvements in J ournal- Boxes,.of which thefo'llowing is a specification.

This means, and more particularly. to a journal boxiacl'aptedto rotatably support a shaft, the shaft beingprovided with means for clerating a lubricant contained within the box, :andl'the, box being, provided WltllrIIlBiLIlS for discharging this lubricant onto the bearing surfaceof the shaft.

IQDG of themain objects .of theinvention is t'OrpITOVlClB a device ofthecharacter stated of simple construction and operation which may be produced. at relatively small; cost.

Aastill further object. is to provide a box or casingrfoncontaining the lubricant having means forpreventing creeping of thealubricant along the shaft. A. still further-object is to provide a box anda shaft rotatably mounted therein, the box having. 'a bearing member for rotatablysupportingi the shaft provided with an opening. communicating direetlyavith the shaft receiving opening .of this member, a disk being secured on the shaft soasitozdip into the lubricant within the casing, the casing being provided with a scraper member engaging the-peripheral surface of the. disk so as to remove :the lubrieantL-from'the same when :the disk and shaft are rotated, "this scraper member being adapted to'dischargeqthe lubricant removed a from the disk through the opening onto the bearing. surface of the shaft. Other objects will appear from {the detailed descriptions In the drawings:

Figure 11 is'a horizontalsectional View taken through a lubricating device constructed in accordance with .my invention on a plane coincident with the under. face of v .thetop of the casing: r

Fig. 2 is ,a-vvertical central longitudinal sectional View: and

Fig.3 is a section taken on -.line.3+3 of E1 1 2 r i I ihe-gcasing 1s composed .of theiupper seeinvention relates to lubricating tion 1 and the lower section 2, which. are releasably secured together by means of screws Sinserted through lugs f and aprovided on the sections 1' and 2, respectively, for this purpose. The upper section 1 is provided, adjacent one end with a partition member or cross-piece 6 extending the full width of the casing a similar member 7 being provided remote from the other end of section 1. MembersG and 7 areadaptcd to cooperate with cross pieces 6 and 7, respectively,.secured in the lower section 2. of the casing. A. hearing beam 8' is secured in the lower section 201? the casing intermediate menibors 6 and 7". This beam cooperates with a beam 9 secured in the upper section 1, these two members forming, a bearing member for rotatabhv receiving a shaft 10. The beams Sand 9 are provided with semi-circular recesses which for-ma circular shaft receiving opening when the easing is assembled, as in Figs. 2 and 3-ofthe drawings.- This bearing member'snugly receives the shaft so asto supportthe same, as shown. The: cooperating partition-members (i'and (Vgand 7 and 7,are also provided with semi-circular recesses which are of such size as to provide shaft receiving openings" 11 and 12 of greater diameter than the shaft 10, the end walls of the sections'l and-2 of the casing being. provided with similar recesses which form the circular shaft receiv ing openings 13 and 14 which are also of greater diameter than the shaft. By this construction, when the casing is assembled, the shaft is mounted for free rotation in the bearing member composed of the beams 8 and 9, the shaft being supported out of contact with the walls of the casing and the partition members.

The ca'singis adapted to contain the lubricant, which is normally maintained at a level slightly below openings 13 and 14 as shown in Figs. 2 and 3 of the drawings. A disk 15 is secured on shaft 10 intermediate the bearing memberandthe partitionmembers-7 and .7, a similar disk 16being secured onthe shaft at the other side of the bearing member intermediatethe same and the partition member-s6 and 6. These two di ks dipinto the lubricant so that, when the shaft is rotated, the disks will raise the lubricant so as to permit the same to be discharged onto the bearing surface of the shaft in a manner to be described.

A cross bar 17 is secured in the upper section 1 of the casing,adjacent the topthereof, above disk 15. This cross bar isprovided, at its longitudinal center, with a.

dovetailed groove 18 which loosely receives a scraper member or brush 19. This scraper has its under facecurved so as to fit snugly against the peripheral face of disk 15 andis provided, at its lower end, with an inwardly projecting and downwardly directed finger 20. a This fingeris so disposed as to extend above the approximately inverted frust opyramidal recess 21 formed at the center of the upper face ofbearing beam 9. This recess communicates with a slot 22 which is indirect communication with the shaft receiving opening of the bearing member composed of beams 8 and 9. The scraper member 19 is freely movable vertically in the cross bar 17, and is normally held snugly in engagement with the peripheral surface of disk 15 by gravity. A cross bar 23 is provided above disk 16', a scraper member 24 similar to member '19 being loosely mounted in this bar for vertical movement and normally held in engagement with the peripheral surface of disk 16 by gravity.

This member 2 1 is also provided with'a finger 25 adapted to discharge the lubricant into the recess 22.

When the shaft-1O is rotated, the disks 15 and 16, which dip into the lubricant, act to raise the lubricant. During the rotation of the disk, the members 19 and 24: scrape the lubricant fromthe peripheral surface of the disk. This lubricant which is thus scraped from the disk, flows downwardly along the fingers 20 and 25 of the scraper members 19-and 24,respectively, and drips into the recess 21 flowing through the slot 22 directly onto the bearing surface of shaft 10. By this means, I insure, that, when the shaft is rotated, the lubricant will be fed directly onto the bearing surface of the same, thus eliminating all danger of excessive heating or burning out of the bearings and avoid the loss of energy due to such heating.

To permit the lubricant to flow, freely within the casing, the lower bearing beam 8 is'spacedabove the bottomof the casing, and partition members 6 and 7 are provided, in their under faces, with, arcuate openings 6 and -71, respectively. As the shaft is rotated, the lubricant is raised by the disks and discharged onto the bearing surface .of the shaft which thusconstantly operates in an oil bath, the excess lubricant flowing back intothe lower's'ection of; the casing. It has been'fou'nd that, when a shaft is rotated in an oil-bath at high speed, the oil is'sucked or drawn to the shaft. This separating the disks 15' and 16 from the main body of the lubricant, this tendency to suck'the' oil onto the shaft is to a large extent eliminated thus effecting a material saving in the lubricant.

This device is intendedmore'particularly as an improvement over my journal box d is.

Patent 7 closed in my United States #1200759, dated October 10', 1916. In this patent I have shown a journal box and a shaft so related as to in'surethat the bearing member for the shaft shall rotate in an'oil bath at all times, the lubricant having-free circulation through the casing of the box. While this device is very good in many cases, I have found that I can'obtai'n better results by constructing thev device in the manner herein described, feeding thev lubricant directly ontothe bearing surface of the shaft through the. medium of. the scrapermembers shown and described. While the principle of operation between this device and the device disclosed in my patent re ferred to are very similar, thespecific constructions of the two devices are materially different, but theyboth involve the broadidea. of the bearing member mounted for rotation in an oil bath and means for'continuously supplying oil to this member.

What I claim is 1. In lubricating means, a casing adapted to contain a lubricant, a bearing member carried thereby for rotatably supporting a shaft and provided with an opening through its upper portion communicating with the' shaft receiving opening of said memhelg'a shaft mounted in said bearing member, a Mllsk carried by saidshaft within thecasing,

and'a Vertically movable scraping member mounted in the casing'above the diskand normally in engagement therewith, said member beingadapted toremove lubricant from the disk when saiddisk' is rotated and having a drip finger projecting above the openingthrough the bearing member so-as to discharge the lubricant removed from the disk into said opening.
